Description
-----------

Recent advances in digital storage and networking, coupled with the extension of
human language technologies (HLT) into ever broader areas and the persistence of
difficulties in software portability, have led to an increased focus on
development and deployment of web-based infrastructures that allow users to
access tools and other resources and combine them to create novel solutions that
can be efficiently composed, tuned, evaluated, disseminated and consumed. This
in turn engenders collaborative development and deployment among individuals and
teams across the globe. It also increases the need for robust, widely available
evaluation methods and tools, means to achieve interoperability of software and
data from diverse sources, means to handle licensing for limited access
resources distributed over the web, and, perhaps crucially, the need to develop
strategies for multi-site collaborative work.

For many decades, NLP has suffered from low software engineering standards
causing a limited degree of re-usability of code and interoperability of
different modules within larger NLP systems. While this did not really hamper
success in limited task areas (such as implementing a parser), it caused serious
problems for building complex integrated software systems, e.g., for information
extraction or machine translation. This lack of integration has led to
duplicated software development, work-arounds for programs written in different
(versions of) programming languages, and ad-hoc tweaking of interfaces between
modules developed at different sites.

In recent years, two main frameworks, UIMA and GATE, have emerged that aim to
allow the easy integration of varied tools through common type systems and
standardized communication methods for components analysing unstructured textual
information, such as natural language. Both frameworks offer a solid processing
infrastructure that allows developers to concentrate on the implementation of
the actual analytics components. An increasing number of members of the NLP
community have adopted one of these frameworks as a platform for facilitating
the creation of reusable NLP components that can be assembled to address
different NLP tasks depending on their order, combination and configuration.
Analysis frameworks also reduce the problem of reproducibility of NLP results by
formalising solution composition and making language processing tools shareable.

Very recently, several efforts have been devoted to the development of web
service platforms for NLP. These platforms exploit the growing number of
web-based tools and services available for tasks related to HLT, including
corpus annotation, configuration and execution of NLP pipelines, and evaluation
of results and automatic parameter tuning. These platforms can also integrate
modules and pipelines from existing frameworks such as UIMA and GATE, in order
to achieve interoperability with a wide variety of modules from different
sources.

Many of the issues and challenges surrounding these developments have been
addressed individually in particular projects and workshops, but there are
ramifications that cut across all of them. We therefore feel that this is the
moment to bring together participants representing the range of interests that
comprise the comprehensive picture for community-driven, distributed,
collaborative, web-based development and use for language processing software
and resources. This includes those engaged in development of infrastructures for
HLT as well as those who will use these services and infrastructures, especially
for multi-site collaborative work.

### Workshop Objectives

The overall goal of this workshop is to provide a forum for discussion of the
requirements for an envisaged open “global laboratory” for HLT research and
development and establish the basis of a community effort to develop and support
it. To this end, the workshop will include both presentations addressing the
issues and challenges of developing, deploying, and using the global laboratory
for distributed and collaborative efforts and discussion that will identify next
steps for moving forward, fostering community-wide awareness, and establishing
and encouraging communication among the various players.

It aims at bringing together members of the NLP community specifically users,
developers or providers of components and tools for these frameworks in order to
explore and discuss the opportunities and challenges in using such platforms for
modern, well-engineered NLP applications.

The challenge of creating reusable and interoperable components raises
particular interest and are affected by legal issues, such as potentially
incompatible licenses of components and tools as well as the technical aspects
of packaging and distribution of components. Also, tools are important, for
example to assemble complex processing pipelines, to manage the bodies of data
that are to be analysed and to visualize, explore, and further deploy the
analysis results. Further challenges are involved in embedding framework based
analysis within applications or using it in distributed computing scenarios,
such as deployment of and access to required resources. Finally, the
preservation of analysis results, their provenance and reproducibility are of
particular interest to the scientific user community.

### Topics

Workshop topics include, but are not limited to:

- processing of very large data collections: scale-out, parallelization, and performance optimization
- advanced applications driven by an NLP framework
- sophisticated tools to build and manage complex processing pipelines
- analysis of results: exploration, evaluation, visualization, and statistical analysis
- experience reports combining components from different sources, as well as solutions to interoperability issues
- experience reports combining different frameworks (e.g. GATE/UIMA/WebLicht/etc.)
- UIMA components with a special focus on genericity and type-system independence
- repositories of ready-to-use components for UIMA and/or GATE
- distribution of components: documentation, licensing and packaging
- developing for UIMA or GATE: simplified APIs, debugging, unit testing, and limitations of the frameworks
- combining annotation type systems in processing frameworks (GATE, UIMA, etc.) with standardization efforts, such as done in the ISO TC37/SC4 or TEI contexts.
- use of NLP frameworks in real-world "industry" settings
- reports on current projects and frameworks, their challenges and proposed or implemented solutions, including efforts to address interoperability
- issues and challenges of multi-site collaborative projects, including reports of implemented or proposed strategies
- pipeline management, including authentication, strategies for passing resources through disparate tools and across hosting nodes, and licensing
- development and use of evaluation environments that facilitate assessment of HLT component performance, iterative application development, and replication of results
- community awareness and implementation of open infrastructures, including how to engage the community, establish confidence in the process, and promote use
